I have Emacs 24 and AUCTex on a Windows 7 machine, however the preview font size is just way too small. Is there a way to make them bigger?

  • Is it possible to put the cursor on the formula? If yes, I'd try M-x customize-face RET.

Add the following to your .emacs file:

(set-default 'preview-scale-function 1.2)

Adjust the value according to your needs.

  • Using the px package from packages-list-packages, this trick doesn't work for changing the font size. Does anyone know why not / what would work? Feb 2 '15 at 14:10

px package uses org-latex, so you can change the preview font size using the scale attribute of the org-format-latex-options settings. I changed it from 1.0 to 1.6. It looks much better.
